This paper presents an enhanced method for the transmission of 3D video in the Multi-view Video plus Depth (MVD) format over Two-Way Relay Channels (TWRC). Our approach addresses the unique challenges of MVD-based 3D video by combining Hierarchical Q

Relay channels capture the essence of several important communication scenarios such as sensor network and satellite communication. In this paper, first, we propose an efficient coding scheme for an additive white Gaussian noise (AWGN) relay channel

In this paper, we mathematically analyze bit-error rate (BER) and diversity order of physical-layer network coding (PNC) scheme in the two-way relay channel (TWRC) under the assumption of multiple antennas at relay node. We assume the quadrature phas

In this paper, the Half-Duplex Relay Channel (HDRC) is thoroughly investigated. Even though this channel model is widely studied, the capacity is not yet fully understood and particularly has not been tightly expressed. In this work, a new capacity e

We propose a Modulated Retro-Reflector (MRR) based Physical-Layer Network Coding (PNC) framework for space two-way relay (TWR) optical communications. MRR PNC simplifies the end node’s design by replacing pointing, acquisition and tracking mechanis

This paper proposes a Polarization-Enabled Digital Self-Interference Cancellation (PDC)-based Full-Duplex (FD) network with an energy-harvesting-enabled source and a Self-Energy Recycling (SER)-enabled relay. The fixed power supply at the relay is on

In recent years, physical layer security has been considered as an effective method to enhance the information security beside the cryptographic techniques that are used in upper layers. In this paper, we provide the security analysis for a two-way r

Abstract We investigate the transmission of a secret message from Alice to Bob in the presence of an eavesdropper (Eve) and many of decode-and-forward relay nodes. Each link comprises a set of parallel channels, modeling for example an orthogonal fre
